I will try it the "Github Action" it seems very useful indeed.

I already found the (extremely obvious and tiny) error that caused all this mess. I am surprised the compile/link system on my Windows machine passed on that without reporting anything. That really threw me off on what the cause may be. Getting back on Linux for development and checks (like I used to use and trust).

Problem solved, moral of the story is never code tired, and use all tools available.
Thank you everyone for your comments and help.

Regards,
Vasilis.

Yes, with all this I can think where I may have messed up. So thanks for the help, at least it verified it is indeed an issue with the code. As far as OSs, I use Ubuntu variants a lot and (on several machines) but these days I have easier access to Windows (with WSL2 btw). I also like a strict compiler (and linker), there is usually a reason why they are strict. So if it is not obvious from examining the code,  I will set up something (be it WSL, VM or Docker) for testing.


          If you have NOT tried "GitHub Action" yet, I highly recommend it.
For my packages, every time I do "git push", it automatically runs "R
CMD build / check" on 5 different platforms -- with no further effort
on my part other than checking the results.


          It should be easy to get something to work following the
instructions in Wickham and Bryan, R Packages[1] or copying the code
from another package.[2] If that fails, you might be able to get help
from this list.  I got valuable suggestions from Dir Eddelbuettel and
Duncan Murdoch.


          I don't know if any version of Debian is available on GitHub
Action. However, if CRAN is rejecting your package on GitHub Action, a
question about that to this list might help make it available.  If you
have special Ubuntu configuration issues that are not provided in the
standard GitHub Action configurations, asking here might help you with
that.


          Hope this helps,
          Spencer Graves

Sounds good, glad to have been of assistance.  On a lark, I also tried your
most recent CRAN release, and it installs and loads fine here.

I love working on Linux. And these days I hear from some friends that having WSL2 on a (recent enough) Windows computer is also good as it effectively gives a second machine with Ubuntu on it.  Docker can also be helpful, as are the online resources -- rhub has helped me with both macos and windows builds.
